It depends on the institution. Some schools like to probe you about your long-term career goals to see if you're a good candidate for their program. UK is INCREDIBLY clinical/post-grad residency driven so they push that agenda but schools like Georgia and Auburn are looking for candidates who may want to practice in a rural setting since they have a need in their individual states so they may structure their situation-based questions around indigent patient care or problems facing rural communities. Are you comfortable stating which school? We might be able to better answer your question.
